Description
Technical field
This utility model belongs to technical field of sealing technology.
Background technology
Existing coal pulverizer reductor seals and uses conventional hermetic, is only to seal with simple rubber sealing, and it is deposited
Shortcoming be: rubber ring type seal when mounted for preventing from touching mill, the most all using gap of going to the bottom is 0.05 0.1mm, top:
0.20 0.25mm, the average seal gap of traditional type oil shelves is big, the probability of the leakage of oil of increase.Reductor runs axis and sealing
Cushion rubber rubs, and causes cushion rubber to damage, and ultimately results in reductor generation leakage of oil.O-ring seal damages fragment and is blocked up by spill port
Plug, make oil not return in fuel tank smoothly, lubricating oil only along at static and dynamic sealing outwardly, cause leakage of oil.
Summary of the invention
The purpose of this utility model is by one independent coal-grinding sealing coal pulverizer reductor spindle nose of design
Machine reductor shaft-head sealing device.
This utility model is to be made up of outer shroud and internal ring, and internal ring is placed in outer shroud central channel；
Internal ring: be made up of left magnetic force oil catch and right magnetic force oil catch, has on left magnetic force oil catch and right magnetic force oil catch
Left-hand thread hole and right-hand thread hole, mate in internal ring fastening bolt is placed in left-hand thread hole and with internal ring clamp nut, internal ring fastening spiral shell
Mother is placed in right-hand thread hole；The interior ring inner surface of left magnetic force oil catch and right magnetic force oil catch composition has guiding gutter, and guiding gutter is with right
Steam vent on magnetic force oil catch communicates, and steam vent side has steam vent catch screw, and the bolt of fixing steam vent catch is installed
In steam vent catch screw；Left magnetic force oil catch and right magnetic force oil catch surface have Magnetitum installing hole；Left magnetic force oil catch and
There is oil guide groove edge the side of the internal ring of right magnetic force oil catch composition, forms oil guide groove between oil guide groove edge and internal ring；
Outer shroud: be made up of two semicircular ring, two semicircular ring are installed by bolt at installing hole, have back on outer shroud
Oilhole, spill port conducting oil guide groove and oil-recovery tank, on the catch fixing hole that catch one end is fixed on outer shroud, the other end suspends.
This utility model simple in construction, low price, eliminate reductor spindle nose leakage of oil..Reductor is in operation due to interior
Ring and outer shroud will not produce friction, so assemblage gap also only has 0 0.05mm gap when mounted, thus decrease leakage of oil
Probability.Internal ring mainly uses import to meet material and makes, and is resistant to 450 DEG C of high temperature above, is in operation and can be produced from lubrication
Effect, extends internal ring service life.

Detailed description of the invention
This utility model is to be made up of outer shroud and internal ring, and internal ring is placed in outer shroud central channel 19；
Internal ring: be made up of left magnetic force oil catch 1 and right magnetic force oil catch 4, on left magnetic force oil catch 1 and right magnetic force oil catch 4 respectively
Have left-hand thread hole 7 and right-hand thread hole 8, in internal ring fastening bolt 2 is placed in left-hand thread hole 7 and mate with internal ring clamp nut 3, interior
Ring clamp nut 3 is placed in right-hand thread hole 8；The interior ring inner surface of left magnetic force oil catch 1 and right magnetic force oil catch 4 composition has guiding gutter
11, guiding gutter 11 communicates with the steam vent 6 on right magnetic force oil catch 4, and steam vent 6 side has steam vent catch screw 5, fixing row
The bolt of pore catch is arranged in steam vent catch screw 5；Left magnetic force oil catch 1 and right magnetic force oil catch 4 surface have magnetic
Stone installing hole 9；There is oil guide groove the side of internal ring of left magnetic force oil catch 1 and right magnetic force oil catch 4 composition along 12, oil guide groove along 12 with interior
Oil guide groove 10 is formed between ring；Through hole 13 is that reductor shaft passes hole.
Outer shroud: be made up of two semicircular ring, two semicircular ring are installed by bolt at installing hole 14, open on outer shroud 17
Having spill port 16, spill port 16 to turn on oil guide groove 10 and oil-recovery tank 18, catch one end is fixed on the catch fixing hole on outer shroud 17
On 15, the other end suspends.Space is left between catch bottom and internal ring outer.
Oil sealing of the present utility model is in operation internal ring and outer interannular is provided with permanent magnet, be in operation due to internal ring with
The effect of outer interannular permanent magnet, internal ring can realize moving up and down, and makes internal ring be under zero gravity operation at any time.Internal ring due to
Being in zero gravity in operation to run, oil shelves ring surrounding and reductor shaft gap are suitable, will not as on traditional oils shelves half gap big, increase
Add leakage of oil amount.
This utility model first measure oil shelves size, and according to size be processed (inner and outer ring dimensional discrepancy 0.05mm with
In).Axial plane cleaning oil pollution is clean, during scuffing original for axial plane, need abraded area is carried out polishing process.Pull down
Old oil shelves, after cleaning, place it in above fresh oil shelves, old the oil end face of shelves and the end face of fresh oil shelves to its, lateral symmetry, in conjunction with
Face keeps consistent, and the hole turned is big 2 3mm than bolt external diameter, so can strengthen shifting amount, be conducive to adjusting outer shroud.As
Fruit occurs and situation about turning joined by casing, after the most first determining the accurate location in casing silk hole, rules in an instant on fresh oil shelves；Join and turned
Bi Hou, does not rushes to assemble, is first fastened with outer gear by outer shroud temporarily, then lower gear is put into cylinder body, see whether radial clearance closes
Suitable.If improper, manual scraping；First inner ring sleeve is fastened on axle, until can not turned position, see that faying face whether can
In enough full contacts, as do not completely attached to, then determine scraping amount according to gap.One time scraping amount is not too big, duty examination,
In case gap is scraped greatly, try first to scrape bright spot with red lead powder every time, then scraped circumference.If still having larger gap, then after internal ring fastening
Need ring combined face in scraping, must note during scraping faying face keeping smooth, the platform of an an angle of 90 degrees, below pad can be looked for
Upper sand paper, is attached to internal ring on an angle of 90 degrees facade, faying face and Sandpapering, it is noted that ensure faying face concordant, internal ring with
Axle fit clearance to control between 0.05 0.10 mm；Install outer shroud time uniform application fluid sealant, require behind location outer shroud with
Casing faying face is concordant, diagonal angle fastening bolt, until outer shroud completely attaches to casing.Zero gravity oil shelves are special due to self
Point, the reductor sealing ring that is in operation automatically is made a concession and is realized axle zero gravity, does not hinder the feature of axle and self-lubricating material, zero gravity oil
Shelves eliminate traditional type oil shelves defect, completely eliminate deceleration machine oil shelves Leakage.
